It’s because of your solitary vice! At least according to “What Ladies Need To Know,” an advice book from 1890. According to which, terrible things will happen to girls who masurbate, including:

They will decline in health and disposition
They will become peevish, irritable, morose, and disobedient
They will become indisposed to activityThey will develop unusual appetites for for mustard, pepper, vinegar, and, (alarmingly?) clay, chalk and charcoal.

Aren’t you glad you live in an age where it’s so easy to get your hands on delicious clay, and you don’t have to hide it in a tea-cup, like the lady in the picture?
